OSSC Pro: Is is possible to support audio out with Extra AV board from Toslink?

[spacetime66]

Is is possible to support audio out with Extra AV board from Toslink Input and if so is there any chance that it could be included in the firmware soon?

I need that feature as I just got an og xbox component cable from TK’s Custom Super Modz and the only one that wasn’t out stock when I order was a component cable that only has Toslink out for audio and My main TV is Sony KV-34910XBR that has only has DVI+RCA video/audio input and I thought the OSSC Pro would supported outputting audio to the Extra AV audio out from Toslink input because it already supports outputting audio to the Extra AV audio out from HDMI…

thanks in advance

It’s not as simple as forwarding I2S stream from HDMI to audio DAC. SPDIF stream needs to be decoded. There are some open code for that (e.g. here), but it will take some time to integrate and test things so we’re talking about months unless someone else could start spending real effort on that soon.

I just looked for an HDMI to DVI adapter with audio adapter, since I have HDMI to VGA adapters with audio, and while I haven’t seen that specifically, there exists something called “HDMI audio extractors”.  With one of those, you likely would still need a 3.5mm stereo TRS to RCA adapter cable (unless it’s included).  I don’t know, but it could be cheaper than an Xbox component cable with stereo audio RCA connectors, that seems doubtful though.

I just looked at what I bought a long time ago for unusual needs: An ROITB STM002 Digital to Analog Audio Converter like this listing on ebay, but other brands exist cheaper: https://www.ebay.com/itm/325365089318

Okay so I got a TOSLINK to RCA converter from amazon and it has fair quality but could be a lot better though… I can wait for the TOSLINK in to Extra AV audio out functionality… hopefully when the OSSC Pro gets the functionality it will result in better audio quality than the cheap converter I got off of amazon https://www.amazon.com/dp/B0BRFVMCJV?psc=1&ref=ppx_yo2ov_dt_b_product_details

After reading the one-star reviews, it sounds like when the OSSC Pro supports it, it’ll definitely be much better.  I haven’t needed to use the one I showed more than once, but it’s just a metal box without an attached cable so I hope it has more longevity than the model on amazon may.  But mine doesn’t support 192 kHz, just 32, 44.1, 48 and 96 kHz.  It also only lists 24-bit, not 16, but I kind of doubt it wouldn’t be supported.
